Don't worry hun you're not stupid. so basically the purple pen means the obvious right? it means that those are the numbers that you will be focusing on first. you are going to make sure that you change them to the same bottom # that way you are able to add them at the very end okay? so what we are going to do is find a # that those bottom #s both go into right? and that would be ten. So what you want to do is multiple top and bottom by the same number to get the denominator to 10. (as pictured) then you will bring both equations down for clean space and add them. like this:
I think I did my math wrong but I got c
Multiply 0.3 by 100 to convert to a percentage. 0.3⋅100.
Simplify 0.3⋅100 0.3 ⋅ 100 .
Your answer is C.) 30%
The correct answer is:
(x + 3)^2 + (y + 2)^2 = 4^2, so the center is (–3, –2)
Further explanation:
The given equation of circle is:
In order to complete the square the terms have to be combined first
9 and 4 will be added to both sides of the equation to complete the square
The next step completes the work
Comparing with the standard form of circle
As the centre is (h,k), the centre of given circle will be:
(-3,-2)
Hence the correct answer is:
(x + 3)^2 + (y + 2)^2 = 4^2, so the center is (–3, –2)

Engineers rely greatly in the international system for measurement, for length this translates to meters hence, for best practice, the answer is meters
<h3>Standard unit for measuring Length</h3>
While other profession will depend on yards, inches, of foot, the standard unit for measurement of length is meters.
The meter is mostly known as the unit for measuring length because it serves as a base unit, other units bigger(Kilometer) or even smaller (millimeter or centimeter) take reference from the meter
